| Tables of some enumerations that pop up in WWT data files. |
These appendices document the following enumerations:
Classifications
“Classification” entries in WTML files can take one of the following values. The default classification is Unfiltered.

Constellations
The following table lists the constellation codes and the center of each
constellation. If a correct code is entered in a WTML file, such as
Constellation="CET", then there can be an improvement in the system’s
performance. If the Constellation field is left blank, or is wrong, then
the RA and Dec entries are used. There are 89 entries in the table, as
the discontiguous Serpens constellation is treated as two separate objects.

Taxonomy
The following table lists the taxonomy codes that can be used to classify images. The AAS WorldWide Telescope has adopted the image hierarchy taxonomy proposed by the International Virtual Observatory Alliance and the Virtual Astronomy Multimedia Project's (VAMP) Astronomy Visualization Metadata (AVM) standard. As an example, a tour of the Sea of Tranquility on the Moon could be classified as Planet → Feature → Surface → Impact.
